WASHING MACHINE.

Application filed December 9, 1922. Serial rNo. 605,759.

The invention relates to washing machines and more` particularly thatclass of washing machines in which the tank or container is mountedV andadapted to oscillate on a zontalv axis. supported by a suitable frame.Tlc primary object of the invention is to improve the connectionsbetween the source of power for operating the machine and theoscillating container or tank.

A further object of the invention is to provide a. connection betweenthe source of power and the oscillating' container or tank of suchcharacter and construction that the tank may be readily and instantlythrown into and out of operative engagement with the source of power. 1

A further object lof the invention vis to so construct the connecting`means between the source of power and the oscillating tank that when thetank is thrown out of operative engagement with the source of power thatthe tank will be automatically locked against oscillating niovement.

A further object of the invention is to so construct the connecting'means between the oscillating tank and source r of power that when theconnecting` means is thrown into the operative position the tank will beautomatically secured in engagement with the connecting' means. f

Other objects of the invention will appear from the followingdescriptionwhich is directed to the preferred embodiment of the invention as shownin the drawings forming impart of the specifica-tion, the novel featuresthereof being more particularly pointed ont in the appended claims.

In. the construction of the improved washing machine, a suitablerectangular supporting frame designated generally by reference tangularframe. The supportingv standards 11 and 12 "are providedy Awithappropriate f braces '14 ext-ending therebetween. The sup porting frameis provided with shelf 15 adjacent. the bottom thereof for the supportof. motor y16, and ygear housing 17 is secured Y. Power shaft 15 ofmotor 16 is connected at its onter end to -d 1ive shaft 19 by anysuitable torsion conplinpas by flexible torsion sleeve Q0, for einample, as clearly shown in Fig. Q of the drawing. Driving shaft 1,9 isjonrnalled in the side walls of housing`17 as at 21. 22 and hasrotatably7 mounted thereon gear wheel 23 meshing with gear wheel 24atlixedl to shaft `25 journaled inthe side walls of housing'l as at Q6,27; Shaft 25 also has nonrotatably mounted thereon geaiwheel 28 in meshwith large rear wheel 29 which is :if-

fixed to shaft `journaled in the side walls of the housing 17 as at 31,32. AShaft 8O has 'tank 13'in` a manner torbe hereinafter described.Tank `13 Vis pivotally supported by the innerendof stub shaft- 39 as at39a.'

Rock sha-ft 41 has affixed to the in ner end thereof clutch shiftingfork member 42 which terminates atits upper .extremity lin spaced apartprongs or shifter members lo,

44 for shifting clutch 45.

The clutch member 45 is provided with opposite sides of the clutchmember are studs 52 and 58 which are formed integrally with the shifterprongs 48 and 44. The rocking shaft 41 ris provided at its outerextrenulv Y with an operatii'lg lever 54 for rocking the shaft 41 tothrow the shifter member 42. liflounted between the corresponding arms46, 47 and 48, 49 respectively, are tubular blocks or collars 55 and 56respectively. rllhese collars 55 and 56 are held in their respectivepositions by clutch pins 57 and 58 which e tend through their respectivecollars and cooperating arns respectively, as shown in Fig. rlhe pins 57and 58 are secured against longitudinal displacement by transverselocking pins 59 and 60, respectively. rlhe clutch pins 57 and 58 Vextendbeyond the inner face of the arms 46 and 48 respectively and are adaptedto have their inner ends engage sockets 61 and 62 in plate 68 secured tothe side wall of the container or tank 18 to oscillate the tank when theclutch member is moved on the sleeve 68L into position shown in Fig. 8by the operation of the rocking shaft 41. The outer ends of the lockingpins pass through bores 64, 65 in rocking arm 87 with their outerextremities flush with the.

outer face of rocking` arm 87 when the clutch is moved inwardly` intoengagement with plate 68, the locking pins being constantly engaged byrocking arm 87 as clearly shown vin Fig. 8. The lower portionof theclutch shifting member 42is formed substantially CII in the shape of theletter Y having branches 66 and 67. To the lower extremity of branch 67is pivotally related extension arm 68 at its upper end and having itslower end passing throughpivotal member 69. and adapted to havereciprocal movement with relation thereto. rlhe arms 67 and 68 form atoggle link arrangement whereby the shifter member 42 may be locked ineither of its eX- treme positions. Pivotal member 69 isV journaled inbracket 70 of frame 10. Around eX- tension arm68 is placed helicalspring 71 which is adapted to exert anr upward pressure on extension arm68 and hold the clutch? shifting member 42 at the limit of its movementin either direction when. moved past its center with relation to pivotal`member 69, Branch 66 of the clutch shifting member 42 carries at itslower extremity shoe 7 2 having curved or turned ends 88 for depressingspring actuated locking pin 74 carried by the bottom portion of thecontainer frame 75 for locking the' container or tank to the frame 10against oscillating movement. The shoe 72 provided at the approximatecenter thereof with socket 78 for the engagement therein, under springtension, of the locking pin 74 which is held yieldingly in position toengage the socket by a spring 74" surrounding the pin and co-operatingwith the bracket 741. f

Shaft 8O has beveled gear 76 for cooperating with suitable gears (notshown) for imparting rotary movementto' shaft 7 7 tor operating wringer78.

ln forming thecontainer vor tank the bottom is carried inwardly andupwardly at the center thereof forming Va batl'le or deflector 79substantially describing in cross section the letter U in invertedposition, and the side walls of the tank are carried downwardly andinwardly at their upper portion as at 8O thus formingl a deflector atthe top portion of the tank which in conjunction with thel detleetor 79at the bottom thereof causes water in the vtank to rsubstantiallydescribe the ligure 8 in its movement when the tank is oscillated.Opening 81 is provided for access` to the tank and cover or lid 82 vispro vided for closing the opening. The formation of deflector 79, asdescribed, in the bottom of thev tank results in producino` dependinglobes 88 and 84 extending longitudinally of the tank, one of suoli lobesbeing on each side of the median line of the bottom of the tank. Drainconduit 85 connecting the low ermost portions of the lobes 88 and 84 hasoutlet pipe. 86 for draining the container. Outlet pipe 86 is providedwith suitable cutoffvalve 87. y y

Gear 28 is frictionally held between collars 89 and 90 under tension ofspring 91 coiled around clutch sleeve 91 thereby providing a slipconnection between gear 25 and shaft 19 which will permit of the driveshaft 19 rotating independently of gear 28 when a load is suddenlytransmitted thereto, which provides for the gradual pickingup of theload by gear 28 and preventing the burning out or other damage vto themotor. Collar 92 carried by clutch sleeve 91l is affixed to drive shaft19 by pin 98 and adapted to ro; tate therewith.

In the operation of the improved washing iio machine herein describedthe clutch 45 is ,i

moved outwardly by the operating lever 54 rocking the clutch shiftingmember 42, disengaging locking pins 57 and 58 fromplate 68, which willsimultaneously lock the container or tank, when in midposition, to the iter or other washing fluid in sufficient quanvlockingv pins 57 and 58thrown into engagement with slots 6l and 62 of plate 63 when thecontainer or'tank 13 will be caused to rock in unison with rocking arm37, the container or tank having been released from its lockingengagement with shoe 72 simultaneously with the shifting ofthe clutch.Any tendency toward sudden strain on themotor will be absorbed bytorsion coupling 20, and by a preferred frictional connection betweengear 23 and shaft 19 so that in the event of an overload the motor willnot be stalled and injured. j Y
